PREFACE 



After more than four years since the appearance of the 2nd edition the 
demand for the International Radio Tube Encyclopaedia is as high as ever and 
its popularity undiminished. 



Since the original issue in 1949, some 9,000 new tube types have been 
released by manufacturers throughout the world. 



To maintain the essentially practical purpose of the work, these new tube 
types have been included in the form of supplements, at the end of the main 
sections. The Encyclopaedia now contains more than 27,500 tube references. 



In order to facilitate reference, the supplements have been further simplified, 
"base diagrams will be found on the same page as that giving the essential 
characteristics or on the page side by side with it. This system eliminates the 
need for cross reference. 



Comprehensive data on all types of microwave tubes including klystrons, 
magnetrons, noise sources, etc., has for the first time been included, thus greatly 
increasing the usefulness of the work. 



It is the earnest hope of the author that this greatly enlarged 3rd edition 
-will provide essential and accurate information to designers and engineers all over 
the world to even a greater extent that was possible with the previous editions. 



Any tube types that have been omitted or where information is scanty is 
Tjecause some manufacturers in remoter parts of the world have been unable to 
•comply with the author's request for information. It is intended to publish extra 
supplements at intervals, these will include new tube types as, information becomes 
available. The author would like to take this opportunity of requesting the 
support of any manufacturer whose products are not included or where information 
is incomplete, to be kind enough to co-operate by sending the publisher details of 
missing types for inclusion at a later date.

ACKNOWLEDGEMENT 



I must express my grateful thanks to members of the B.V.A. and other 
manufacturers throughout the world for their very kind co-operation in supplying 
information — often at considerable trouble to themselves — without whose help this 
book would not have been possible. 

Information on the British Services, R.A.F., Royal Navy, British Army and 
G.P.O. tube types is a British Crown Copyright, reproduced by permission of the 
Controller of Her Brittanic Majesty's Stationery Office. 

Without the help of my Secretary, Miss Maisie Johnson, my labours would 
have been very much heavier.

At the back of the 10 main sections will be found a supplementary list for sections 1-9 which includes 
tubes, details of which were received too late for classification in the main sections. 

In all the above sections, the tube listing is strictly numerical and alphabetical, the number taking 
precedence in all cases. Example : Tube type 6A8 is listed prior to type 6AB7. 

Tube Base Charts covering the Pin Numbers and general appearance of every known type of base 
will be found on pages 402 to 407. The Base Classification Numbers, i.e., G8A, USM6, P8, 
etc., are listed similarly to the tubes in Sections 1 to 9, numerically and alphabetically with 
number precedence.
